(Severe cold, dizziness, forgive me for typos.) There are still a few PPTs of work that have not been done, I went to a meeting a few days ago, and the update will not be too stable before the National Day, sorry. ）

Dr. Z said with a blank face, "I don't understand what you mean. ”

Liu Zheng put his finger into one of the cups of Coke, picked up an ice cube and said, "The invisible ruby is in this ice cube." ”

When Dr. Z heard this, he disappeared, and Xuanyuan's terrifying consciousness appeared.

"You're right, but you have to tell me how you deduced it, and I don't think you're guessing, because there are 10 ice cubes in the two cups, and the one in your hand is indeed the one with the gem."

Liu Zheng put the ice cube on the table, the ice cube was nothing special, and if there was really a gem hidden in the ice cube, he couldn't see it, because the gem had already been coated with an invisibility potion.

Liu Zheng pointed to the physics book area and said: "Just now I found that strange place, I asked the doctor, but the doctor gave a very surprised reply, he said that his physics is very poor, this answer is very credible, because the books are very new, and neatly stacked together, obviously untouched, should be prepared for his new assistant as he said."

But how bad is the doctor's level of physics? I didn't ask it, I felt that this question could not be asked, and if I did, it might cause some unnecessary trouble, so I chose to continue to observe. ”

After a pause, Liu Zheng turned around, looked around the entire laboratory and said: "The whole laboratory is out of the sky, and the hint you gave me asked me to find an invisible ruby the size of a button in such a messy place, it is like looking for a needle in a haystack."

So I looked for 5 minutes and understood, even if I was given a few hours, let me look in this garbage heap, I couldn't find the ruby, only by continuing to get the key hint, it was possible to find the whereabouts of the ruby, and the key hint is divided into two aspects, on the one hand, you still have to observe, through the law of complexity and simplicity of the madman Yan, the complex clues look at the general, to think simple, so I noticed the existence of physics books, thinking that this is a hint.

Also, I knew from the beginning that Dr. Z was there to prepare me for a hint, otherwise you wouldn't have to set up this NPC, so I tried to start talking to him.

As soon as the conversation box was opened, I couldn't hold it, after I got the information that his physics was very poor, I noticed the refrigerator in the corner again, and after looking around again, I felt that it was almost there, so I began to relax the atmosphere, saying that the doctor should not be a thief who stole gems, and said that he was thirsty and wanted to drink the drink in the refrigerator, and the doctor replied to me that there was only Coke in the refrigerator, of course I had no reason to refuse, and then I pretended to sit on the chair as if nothing happened, but in fact, when the doctor added ice, I stared at him deadly, I saw him put 5 ice cubes in each of his two cups.

And then when he took the cup and guess what, I actually only saw a total of 9 ice cubes floating on top of the cola in the two cups, as long as anyone who is a little proficient in physics knows that the density of ice cubes is smaller than that of water, so it will inevitably float on the water, now there are 9 pieces floating on the coke, and the other one disappears, it must be sinking, which means that the density of the sinking ice cube is greater than that of water, then there is only one possibility, that is, the gem is frozen in the ice, resulting in an increase in weight, Thus unable to float on the surface of the cola. ”

After a pause, Liu Zheng continued: "Actually, I started to suspect when I saw the refrigerator, the laboratory is generally a very rigorous place, and it is unlikely that there will be such a thing as a refrigerator, even if you want to freeze some materials, you will only use a freezer, not a refrigerator."

And when the doctor said that there was only Coke, my suspicion was further confirmed to a certain extent, that Coke is black, and if you hide the gem in Coke, it is not easy to see with the naked eye. And when the doctor said that he wanted to add some ice, I realized that eighty percent of the gems were frozen in the ice.

Then I watched carefully as the doctor placed a few ice cubes, and finally figured out which one contained the gem. ”

The surroundings went dark, and when he regained consciousness again, Liu Zheng found that he had returned to the clouds, and he was still sitting on the seesaw.

Feng Yan closed his eyes and shouted: "Are you releasing water, such a simple puzzle, the gap between us is so easily pulled back?" ”

Xuanyuan ignored Feng Yan and snapped his fingers, and the seesaw returned to its equilibrium state.

Liu Zheng saw that the seesaw had regained its balance, and he was in a good mood, and said: "Save some effort, look at your stupid look, it's a shame, there are many people watching your live broadcast outside." ”

Immediately after, Xuanyuan said in a dream: "It's your turn again, long-haired brother." ”

The next moment, Feng Yan was once again pulled into the spiritual space.

After regaining consciousness, Feng Yan sat in a car, he was in the driver's seat, holding the steering wheel, and the car was driving unhurriedly.

"Wow, you're an old driver again?"

This is the third time Feng Yan has driven in the game, and to be honest, he still likes to drive very much.

At this time, the scenery on both sides of the car is very single, it seems that it should be a certain main road, and there is not a single ghost on the road, and there is no hint.

"Hey~ What's going on, give me a little hint, otherwise I don't even know what I'm going to do."

Feng Yan shouted a few words, but there was no response, he wanted to stop, but found that the brakes were useless, and there was no response when the accelerator was pressed, and the car drove at a constant speed.

'Ding Dong', suddenly a short but familiar voice came from the cabinet in front of the passenger of the car, Feng Yan was about to start searching the car.

After seeing the obvious prompt, he did not hesitate to open the cabinet in front of the co-pilot, and found that there was an Apple mobile phone inside, he pressed the home button, and found that there was an unread WeChat prompt on the screen, Feng Yan guessed correctly, just now it was the prompt sound of receiving WeChat, which belonged to the original prompt sound, that is, the kind of prompt sound that was used by the most people, so when he heard it, he felt very familiar, and immediately judged that there was a mobile phone in the cabinet.

"Huh?"

Feng Yan swiped the screen and tried to enter the WeChat APP interface, but found that after swiping the WeChat prompt message, the interface that appeared was Please enter the password, and it was a 6-digit password.

"It seems that you want to kill me, but it's quite kind, and it's not encrypted with fingerprints."

Feng Yan smiled, turned off the mobile phone screen, turned on the lights in the car, and looked at the lights to see if there were any fingerprints on the screen that often entered the password, which was left behind, if there were, through simple sorting, try a few more times, it should be unlocked soon, but unfortunately, the mobile phone screen is as clean as new, without any fingerprints.

"It's kind of interesting." Feng Yan smiled even brighter.

He didn't put down the phone in a hurry and began to look for clues about the password in the car, but pressed the HOME button again, the screen lit up again, he pondered for a second, slid up from the bottom of the screen with his thumb, and suddenly the hidden interface appeared, this is the interface setting of the Apple mobile phone, through the hidden interface, you can quickly achieve what you want to do immediately without unlocking.

There are four shortcut options in the hidden interface below: Flashlight, Time (including World Clock, Alarm, Bedtime, Stopwatch, and Timer), Calculator, and Camera.

These four shortcut options can be clicked directly in,You don't need a password to do some simple operations,Feng Yan didn't hesitate to click to the calculator option,After entering the calculator interface,He found,There is a string of 6-digit numbers in the calculator interface,Because the calculator function is memorable,That is to say,The value after input and calculation,It will not be zeroed due to exiting the interface,Unless the user himself zeros。

Obviously, this string of numbers should have been left behind after someone entered it before and did not return to zero.
